Courui D01 mod thread, my take on the process and it lives. mattlward

Dang! I read your thread a few minutes after the first mystery box was claimed. I don't know how I missed the heatsinks.

That's the heatsinks I had

I took the first mystery box. I am low on mod parts and have missed a couple of good deals on a decent volume of modding stuff and got to this one on time, and I also took the heat sink. Not the one with an LED, I have no real use of the big LED.

I am not sure how I will connect and mount the LED in this beast. I hate to file on the side of the reflector and I do not have a good copper at 26 mm. I am planning to use that copper strip, bent, insulated and soldered to the star in place of wires since the copper is so thin.

You can use painters tape, and tape the top and bottom of the reflector up, and if you have a drill or air grinder with sanding pads sand/grind the base for clearance. Or you have a lot of hand filing and sanding? Might have to open up the diameter of your heat sink step.I have used these for xm-l2’s Maxtoch XM / XHP50 31.5mm Copper MCPCB and these for xpl’s http://www.mtnelectronics.com/index.php?route=product/product&path=63_64&product_id=401

you started a nice project.

It lives! Updated in OP!

great work ,kaidomain reflector ?:slight_smile:
i am interesting for the contact board is they are still available pm for price and shipping to europe if you can ship,thanks.

Looks very clean, Matt.

I’m tempted to order a few of your contact boards in my next OSH order.

We have a new guy at work, & he’s into camping, etc., & is chasing a thrower.

I’m going to lend him my D01, & I have a feeling I’ll be building a few more…. :slight_smile:

OP updated!

Looking good!

Wight, does that look like proper focus? I am not really sure how that hole it the beam should react when focus is correct. I am going to do the tail switch next and I need to rebuild Star momentary to remove the 0 output mode and reflash the driver. I am thinking about using that copper strip to attach to the star and extend thru the headsink with heatshrink tube to insulate it and then solder the wires in the driver compartment. Should allow the reflector to sit a little lower.

From my experiance you will get best focus if the reflector is sitting directly on the MCPCB and the centering ring is inside refl. opening…

Hah, you’re asking the wrong member! I saw your question and I’m just as curious as you are about the answer. Learning about proper LED focusing techniques has been on my to-do list for a while now.

It’s probably reasonable that the properly focused beam has a doughnut close up.

I did specifically ask lightme about a focusing technique mentioned in this thread: Convoy S2 Long Range Thrower Mod The response is in post #23 and honestly I’m not sure that I have a handle on it yet. Before asking more questions I thought I’d give it a try and I haven’t had an opportunity to do that yet.

Something like this

Matt, have you seen the post I made about D01 focus testing?

I did, I think I need the reflector a little lower. That is why I am considering using the copper strap instead of wire to the star.

And so the “high rise” driver mounting method is born? Very nice job!

Thanks Hoop, I love the way that driver mounted up. I did not want to have to glue it into place and my skills with Eagle were not good enough or I would have integrated the driver right on the contact board.

Yea, it looks great.

Might be worth pointing out to folks that high rise mounting should probably only be done with drivers that don’t need really need to be heatsinked, such as FET or FET+1.

Yes, did not think to mention that. A 7134 driver, or some of the buck/boost drivers might not like it. Although, with 4 copper straps to draw heat it might not be a huge problem. Not sure. I love the way it worked out here!
